Bug #48463 backporting from 6.0-rpl to celosia a set of bugs
The mentioned on the bug report set of bugs fixes have not be pushed to the main trees.
Fixed with extracting commits done to 6.0-rpl tree and applying them to the main 5.1.
Notes.
1. part of changes - the mtr's specific - were packported to the main 5.0 tree for mtr v1
as http://lists.mysql.com/commits/46562
However, there is no that fix anymore in the mtr v2. (This fact was mailed to mtr maintaining
people).
2. Bug@36929 crash in kill_zombie_dump_threads-> THD::awake() with replication tests
is not backported because the base code of the patch is libevent and that was removed
from the main trees due to its instability.
